Multiquip EM98078 6" Muffler Clamp

The Multiquip EM98078 6" Muffler Clamp is a genuine OEM replacement designed for Mayco concrete pump models C30HDNI, C30HDN, and C30HDG. As a direct OEM part, EM98078 is manufactured to the same specifications as the original component, ensuring a correct, secure fit on the exhaust system. This clamp is compatible across the C30 series lineup, including C30HDNI Precision and C30HDNI Zenith variants.

Key Features

• OEM-Grade Clamping Force — Manufactured to original torque and material specifications, maintaining a gas-tight seal on the muffler connection.
• Direct Bolt-On Replacement — Matches the original mounting hardware and 6" diameter profile for a straightforward swap with no reworking of the exhaust assembly.
• Broad C30 Series Compatibility — Fits C30HDNI, C30HDNI Precision, C30HDNI Zenith, C30HDN, and C30HDG Mayco concrete pump models.
• Exhaust Integrity Maintained — A properly secured muffler clamp keeps exhaust gases routed safely away from the operator and engine components, preserving correct back-pressure for the exhaust system.
• Exhaust Safety Compliance — Keeping the muffler clamp in sound condition prevents exhaust leaks that can expose operators to carbon monoxide and create fire hazards near the engine bay.

A muffler clamp holds the muffler securely to the exhaust pipe or manifold outlet, creating a clamped, leak-free joint in the exhaust system. On a concrete pump like the C30 series, maintaining a tight exhaust connection is critical — a loose or failed clamp allows hot exhaust gases to escape at the joint, which can damage nearby hoses and wiring, increase engine noise, and expose operators to harmful fumes. Replacing a worn or broken clamp promptly restores the integrity of the exhaust path and keeps the machine operating safely in the field.
